PLOW.

Application filed November 29, 1920.

.To @ZZ fac/icm t may concern Be it known that I, MARCELO CONTI, subject of the King of Italy, and resident of Buenos Aires, in the Republic of Argentina, have invented certain new and useful Improvements in Plows, of which the following is a specification.

rlhis invention relates to certain new and useful improvements in plows, and has for its object a particular arrangement for a resilient. and jointed mounting of the rolling colters, whereby the usual drawbacks inherent to the construction of said part, as actua-lly used, are entirely eliminated.

It is well known that the purpose of the rolling colter arranged on the plow beam in front of the share, is to vertically cut the band of soil to be detached and turned over by the share and mouldboard. To perform this cutting operation, the disk acts after the manner of a wheel by turning round its axle and when encountering an obstruction, such as a root, stalk, weeds or the like, the said disk tends to rise. As normally the colter disk is rigidly connected to the beam of the plow, the rising effort caused by the obstruction, will be transmitted to the en` tire body of the plow which will jump about and even get out of the furrow, thus doing very uneven and imperfect work. For this reason, many farmers prefer to entirely dis` pense with the use of the rolling colter, but it is also well known that such elimination seriously affects the appropriate tillage of the soil.

In order t0 avoid the above objections, I have devised the resilient improved colter above referred to, a representation of which is given in the accompanying drawing which shows a side elevation of part of the plow beam provided with such colter.

The fork A which carries the rolling colter D, is pivoted at its front end at H to the lower rear portion of a sleeve B through Specification of Letters Patent.

which passes the lower end of a vertical standard E by means of which the attachment as a whole is secured to the plow beam with the aid of 'the sleeved fitting F, said fitting having the Lipper end of the standard extending through it. A suitable spring C is provided for the purpose of exerting a downward pressure on the fork A whenever, owing to the resistance opposed by the soil or any obstruction encountered by the colter D, this latter should tend to emerge from the furrow, the front end of the spring being fastened to sleeve B above the point of pivotal connection H, and the rear end of said spring bearing upon the rear portion of said fork.

It will be evident that several modiiications of construction and detail may be in` troduced into this invention, without de` parting from the scope and limits thereof, `as hereinafter claimed.

Having now described my said invention, I declare that what I claim as new and desire to secure by Letters Patent, is:

A plow attachment comprising, in combination, a sleeved fitting adaptedv for connection to a plow beam; a vertical standard extending at its upper end through said lit-ting and supported thereby; a sleeve mounted on the lower end of said standard; a. fork pivoted at its front endto the lower rear portion of the last-named sleeve; a rolling colter journaled in the free rear ends of the branches of the fork; and a spring attached at its front end to said last-named slee above the point of pivotal connection of the fork thereto and bearing at its. rear end upon the rear portion of said fork so as to yieldingly press the latter and the colter downward.
